Few rom-coms offer as much colorful costume inspiration as *13 Going on 30*. The 2004 movie blends playful 1980s details, glossy Y2K fashion, magazine-editor glamour, and memorable partywear. Jenna Rink’s rainbow-striped party dress remains the standout, but her pajamas, floral dresses, office looks, and youthful accessories provide plenty of recognizable alternatives. Lucy, Matt, the Six Chicks, and the Poise team also make excellent choices for couples and groups. () Every look below includes clothing, hair, makeup, accessories, props, and footwear, making it easy to recreate from thrift-store pieces or items already in your closet. Whether you need a birthday outfit or nostalgic Halloween look, these 35 13 going on 30 costume ideas cover the movie’s most memorable fashion moments.

1. Jenna Rink Rainbow Dress Costume

Jenna Rink’s rainbow party dress is the movie’s most recognizable costume. Choose a fitted mini dress with diagonal stripes in turquoise, lime green, purple, pink, and brown. If you cannot find an exact replica, layer a bright green camisole beneath a colorful striped dress. Add a chunky butterfly necklace, pink shoulder bag, matching bracelets, and metallic teal or silver heels. Wear long brown hair straight with two small front sections pinned back. Finish with pale blue eyeshadow, glossy pink lips, rosy cheeks, and a cheerful smile. A small Poise magazine prop helps explain the character before the dancing starts. This colorful head-to-toe look works especially well for Halloween parties, 30th birthdays, and nostalgic movie events.
2. Jenna Rink Pink Slip Dress Costume

For a comfortable costume that fans will quickly recognize, recreate Jenna’s confused first morning as a 30-year-old. Start with a knee-length pink satin slip dress or soft nightgown with narrow straps. Layer it with a lightweight robe if you want more coverage. Wear a colorful sleep mask pushed onto your forehead and carry a cordless phone, fluffy pillow, or fashion magazine. Keep brown hair loose, slightly tousled, and naturally straight. Makeup should look fresh and sleepy, with light concealer, soft pink blush, mascara, and tinted lip balm. Complete the look with fuzzy pink slippers or flat satin mules. This Jenna Rink costume is easy to assemble, comfortable for long events, and perfect for a last-minute movie-themed party.
3. Jenna Rink Blue Pajama Costume

Jenna’s blue pajama look offers a cozy alternative to the famous striped dress. Wear a matching pale blue pajama set with a sleeveless or short-sleeved top and relaxed trousers. Add a bright pink-and-orange fringed cardigan to capture her playful approach to adult clothing. Style brown hair loose and straight, using a simple side part. Choose minimal makeup with soft blue shadow, pink blush, mascara, and glossy lips. Carry a small handbag, apartment keys, or a rolled-up magazine as your prop. Finish with flat mules, ballet flats, or clean slippers if the event is indoors. The combination should look intentionally mismatched and youthful rather than polished. It is an excellent warm, practical costume for a casual Halloween gathering or group movie night.
4. Jenna Rink Green Floral Dress Costume

A green floral dress captures Jenna’s softer style as she becomes more thoughtful and reconnects with her younger personality. Choose a fitted or gently flared dress with a green background and colorful flower print. Tie a narrow pink ribbon around your waist or hair for extra movie-inspired detail. Wear brown hair in a smooth half-up style with face-framing sections. Use fresh makeup with rosy cheeks, pale shimmer on the eyelids, mascara, and pink lip gloss. Add a small pastel handbag, butterfly necklace, and a Poise folder or magazine. Complete the outfit with pink kitten heels, neutral sandals, or simple pumps. This feminine costume is subtle enough for work-friendly celebrations while still looking recognizable when paired with the right early-2000s accessories.
5. Jenna Rink Red Floral Top Costume

You can create a casual Jenna Rink costume without purchasing a special dress. Begin with a fitted red floral blouse or camisole and pair it with medium-wash bootcut jeans. Add a narrow belt, colorful shoulder bag, and small butterfly or heart necklace. Wear long brown hair straight with a side part or pull the upper sections into a relaxed half-up hairstyle. Keep makeup bright and youthful with blue-gray eyeshadow, rosy blush, mascara, and shiny pink lips. Carry a bag of fruit-flavored candy or a handmade Poise magazine as a recognizable prop. Finish with pointed kitten heels, platform sandals, or early-2000s-style ankle boots. This easy costume feels wearable and relaxed while still capturing Jenna’s colorful, optimistic approach to adult fashion.
6. Jenna Rink Pink Office Costume

Bring Jenna’s fashion-editor career into the costume with a polished pink office look. Wear a fitted pink blazer over a coordinating blouse or camisole, then add a knee-length skirt or tailored trousers. Choose a structured shoulder bag, colorful necklace, slim watch, and folder labeled “Poise” to establish the magazine setting. Style brown hair in a smooth blowout with soft volume at the ends. Makeup can include frosted eyeshadow, defined lashes, warm blush, and glossy rose lipstick. Wear pointed pumps or kitten heels in pink, cream, or metallic silver. A press pass or pretend editorial calendar makes another useful prop. This complete costume is appropriate for an office Halloween event and gives fans a sophisticated alternative to Jenna’s brighter party dress.
7. Jenna Rink Camel Jacket Costume

Jenna’s camel-colored jacket and playful updo create a distinctive early-2000s costume. Start with a fitted tan faux-leather jacket over a colorful blouse, then wear dark tailored pants or a knee-length pencil skirt. Twist brown hair into a messy bun and secure it with decorative hair sticks. Choose bronze eyeshadow, peach blush, defined lashes, and pink gloss. Add a compact shoulder bag, oversized sunglasses, hoop earrings, and a stack of fashion magazines. Pointed brown boots or neutral heels complete the outfit while keeping it practical. The combination of a professional jacket and youthful hair accessory reflects Jenna’s unusual mix of adult responsibility and teenage enthusiasm. It is a clever choice for fans who want something recognizable but less commonly recreated.
8. Jenna Rink Black Office Suit Costume

For a sleek magazine-office costume, recreate Jenna in a fitted black suit. Choose a single-button blazer and matching trousers or pencil skirt, then add a colorful satin camisole underneath. Bright accessories keep the outfit connected to Jenna’s playful personality. Wear a butterfly necklace, pink shoulder bag, and narrow tinted sunglasses. Style long brown hair straight and smooth with a polished side part. Apply subtle blue eyeshadow, mascara, rosy blush, and glossy pink lipstick. Carry a mock Poise magazine, clipboard, or folder filled with pretend editorial layouts. Finish with black pointed pumps or ankle boots. This understated costume works well for workplaces and cooler weather. It can also become part of a larger Poise magazine group costume with Lucy and other editors.
9. Jenna Rink White Blouse Costume

A crisp white blouse outfit creates an easy DIY version of Jenna’s professional wardrobe. Wear a fitted button-front blouse tucked into a colorful knee-length skirt or tailored black trousers. Add a wide belt, short necklace, bright handbag, and early-2000s sunglasses. Brown hair should be smooth and bouncy, either worn down or gathered into a neat ponytail. Choose fresh makeup with soft shimmer around the eyes, pink blush, mascara, and a glossy neutral lip. Carry a binder marked “Poise Redesign” or a stack of handmade magazine covers. Finish with kitten heels, pointed pumps, or tall boots depending on the weather. This costume is simple enough to build from office clothing but becomes clearly movie-inspired through the props and playful Y2K accessories.
10. Jenna Rink Green Corset Costume

Create a bold Jenna-inspired office look with an olive or green corset-style top layered over a fitted blouse. Pair it with a knee-length skirt or tailored trousers so the costume remains comfortable and public-event friendly. Add a cropped jacket if you want more coverage. Wear brown hair in a structured updo with decorative hair sticks or a smooth high ponytail. Use neutral green eyeshadow, rosy blush, mascara, and glossy pink lips. Accessorize with a colorful shoulder bag, pendant necklace, editorial folder, and narrow sunglasses. Complete the look with pointed boots or simple pumps. The fitted green layer and unusual office styling capture the experimental fashion associated with Jenna’s magazine wardrobe while giving you a costume that feels different from the frequently copied rainbow dress.
11. Young Jenna Birthday Costume

Recreate young Jenna Rink at her 13th birthday with a sweet 1980s party outfit. Choose a floral or pastel dress with puffed sleeves, a fitted waist, and a modest knee-length skirt. Add white ankle socks, simple flats, a friendship bracelet, and a handmade “30, Flirty and Thriving” magazine page. Style brown hair with fluffy volume, curled bangs, and a bright scrunchie or ribbon. Makeup should be minimal and age-appropriate, using only light blush and tinted balm when needed. Carry a decorated birthday invitation, a small box of wishing dust, or a dollhouse prop. This nostalgic costume is especially suitable for teens and family-friendly events. Its mix of birthday details and period styling makes the character clear without requiring an expensive replica.
12. Young Jenna School Costume

Young Jenna’s everyday school look is ideal for a simple, comfortable costume. Wear a colorful patterned sweater or knit vest over a collared shirt, then add high-waisted jeans or a pleated knee-length skirt. Finish the clothing with white socks and classic sneakers. Style brown hair in a high side ponytail with a scrunchie, leaving the bangs softly curled. Keep makeup natural with a little rosy blush and clear lip balm. Carry a school binder decorated with magazine clippings, a bag of colorful candy, and a friendship bracelet from Matt. A handmade Poise cover can be tucked inside the binder for extra context. The result should feel authentically 1980s, slightly awkward, and youthful, capturing Jenna before her magical transformation into a fashion editor.
13. Young Matt Flamhaff Costume

Young Matt’s costume combines approachable 1980s clothing with his creative personality. Wear a striped sweater, plaid button-down shirt, or casual windbreaker with relaxed jeans. Add white athletic socks and retro sneakers. Style short brown hair neatly but not too perfectly, and skip elaborate makeup beyond natural complexion products. Carry a homemade camera, friendship bracelet, or miniature dollhouse as the main prop. You can also hold a bag of colorful candy to reference his friendship with Jenna. A school backpack decorated with small patches gives the outfit more period detail. This character works well for men, teens, or anyone who prefers a comfortable costume without formal clothing. When paired with young Jenna, the clothing and heartfelt props create an instantly charming duo.
14. Adult Matt Photographer Costume

Adult Matt’s understated photographer look is practical and easy to recognize beside a Jenna costume. Wear a neutral button-down shirt under a brown, olive, or charcoal jacket. Add straight-leg dark jeans or casual trousers with brown boots or clean sneakers. Keep short hair slightly tousled and use natural, barely visible makeup. The essential accessory is a camera worn around the neck, preferably with a vintage-looking strap. Carry a messenger bag, photo envelope, or miniature model house to add another connection to the story. A simple watch completes the head-to-toe look. This costume deliberately contrasts with Jenna’s colorful wardrobe, so avoid bright patterns. It works particularly well as one half of a couple costume featuring Jenna’s famous party dress or floral outfit.
15. Lucy Black Party Dress Costume

Lucy’s black party outfit offers a sharper alternative to Jenna’s rainbow dress. Choose a fitted black cocktail dress or a modest black two-piece set with lace sleeves or textured panels. Add sleek black heels, a compact clutch, silver earrings, and a slim bracelet. Style dark blonde or light brown hair in a smooth blowout or elegant updo. Makeup should look more polished than Jenna’s, with charcoal eyeliner, defined lashes, sculpted blush, and berry lipstick. Carry a Poise magazine or editorial folder to establish Lucy’s competitive fashion-industry role. A small event badge also works as a prop. This sophisticated costume is ideal for someone who prefers neutral colors but still wants to join a movie-themed group or recreate the memorable party dance scene.
16. Lucy Green Satin Costume

A rich green satin outfit reflects Lucy’s sleek and competitive style. Wear a fitted green camisole dress or satin top with a coordinating midi skirt. Add a tailored black blazer if you need warmth or extra coverage. Choose black pointed heels, a structured shoulder bag, delicate jewelry, and narrow sunglasses. Style light brown or blonde hair in a smooth side-parted blowout. Makeup can include defined brows, brown eyeliner, soft contour, and muted berry lipstick. Carry a mock Poise issue with Lucy’s name written on the editor page. A clipboard or presentation folder strengthens the magazine-office theme. The finished costume should appear controlled and fashion-forward, providing a visual contrast to Jenna’s colorful, childlike combinations. It works for solo wear or a Jenna-and-Lucy duo.
17. Lucy Camel Jacket Costume

Lucy’s camel jacket costume combines early-2000s office fashion with a polished, slightly intimidating mood. Wear a fitted tan jacket over a black camisole and pair it with a slim pencil skirt or tailored trousers. Choose dark pointed boots, a structured handbag, simple gold earrings, and tinted sunglasses. Style blonde or light brown hair in a straight blowout or low twist. Use defined eyeliner, matte foundation, soft contour, and neutral rose lipstick. Carry a folder of pretend magazine layouts or a Poise competitor cover as your prop. Keep the overall color palette controlled rather than playful. This look is comfortable enough for work and easy to assemble from thrift-store pieces. Beside Jenna’s colorful camel-jacket version, it also creates a clever matching-but-competitive duo costume.
18. Young Tom-Tom Costume

Young Tom-Tom needs a confident 1980s outfit that clearly separates her from shy young Jenna. Wear a colorful cropped jacket or patterned sweater with a high-waisted denim skirt and bright leggings. Add scrunched socks, white sneakers, plastic bracelets, and bold clip-on earrings. Style light brown hair in a high side ponytail with teased volume and a large scrunchie. Keep makeup age-appropriate with light blush and tinted lip balm. Carry a school notebook marked “Six Chicks” or a decorated birthday invitation. A small candy bag adds another connection to the party scene. The outfit should feel coordinated and noticeably trendier than Jenna’s school clothing. This costume is excellent for teens, nostalgic adults, or anyone joining a larger Six Chicks group.
19. Six Chicks Group Costume

Gather six friends for a colorful Six Chicks costume inspired by 1980s middle-school fashion. Each person can wear a different combination of patterned sweaters, denim skirts, leggings, oversized jackets, bright socks, and white sneakers. Coordinate through matching friendship bracelets, colorful hair scrunchies, and notebooks labeled with the group name. Hair should feature side ponytails, curled bangs, teased volume, or ribbon-tied half-up looks. Keep makeup playful but family-friendly with rosy cheeks, pastel shadow, and tinted lip balm. One person can dress as Tom-Tom and stand at the center holding a birthday invitation. The others may carry school binders, candy bags, or magazine clippings. Consistent accessories make the group immediately cohesive even when everyone uses clothing already available at home.
20. Jenna And Lucy Party Costume

Jenna and Lucy make a strong two-person costume because their contrasting party wardrobes communicate their personalities. Jenna should wear a colorful diagonal-striped mini dress, butterfly necklace, pink bag, and metallic heels. Lucy can wear a fitted black lace cocktail dress with black pumps and a sleek clutch. Give Jenna long brown hair with pinned-back front sections and bright blue eye makeup. Lucy’s light brown or blonde hair should appear smooth and polished, paired with defined eyeliner and berry lipstick. Both people can carry Poise event passes or magazines. Practice a short synchronized dance pose for photos rather than bringing extra props. This duo is recognizable, visually balanced, and particularly effective for best friends attending a Halloween party or movie-themed birthday celebration together.
21. Jenna And Matt Couple Costume

For a romantic couple costume, combine Jenna’s colorful party outfit with Matt’s quiet photographer wardrobe. Jenna can wear a rainbow-striped mini dress, butterfly necklace, pink shoulder bag, glossy makeup, and teal or silver heels. Her brown hair should be straight with the front pieces pinned back. Matt should wear a neutral button-down shirt, brown jacket, dark trousers, and casual boots. Add naturally styled short hair and a camera around his neck. He can carry photographs or a miniature dream-house prop, while Jenna holds a Poise magazine. Their dramatically different color palettes make each role easy to identify. The couple can pose as if Matt is taking Jenna’s picture, creating a sweet and recognizable photo opportunity without needing complicated scenery or expensive costume pieces.
22. Young Jenna And Young Matt Costume

Young Jenna and Matt create a nostalgic duo based on friendship rather than formal party glamour. Jenna should wear a pastel floral dress or colorful sweater with a knee-length skirt, ankle socks, and flats. Style her brown hair with curled bangs and a bright scrunchie. Matt can wear a striped sweater, relaxed jeans, and retro sneakers with short, neatly tousled hair. Keep makeup natural for both costumes. Jenna may carry a Poise magazine clipping and decorated birthday invitation, while Matt holds a handmade dollhouse, camera, or friendship bracelet. A small container labeled “wishing dust” connects the two looks. This comfortable costume is appropriate for couples, siblings, best friends, or teens and can be assembled almost entirely from thrifted clothing and simple craft supplies.
23. Jenna And Matt Wedding Costume

The final wedding scene provides a romantic, less obvious costume for couples. Jenna can wear a simple sleeveless white or ivory wedding dress with a softly flared skirt. Add delicate jewelry, natural pink makeup, and brown hair styled in a smooth half-up look or relaxed curls. Choose comfortable white pumps or ballet flats and carry a small bouquet of pastel flowers. Matt should wear a dark suit with a white shirt, understated tie, polished shoes, and neatly styled short hair. He can carry a camera or miniature model house to make the movie connection clearer. Jenna may hold a small bag of colorful candy. This couple costume feels elegant and wearable while representing the characters’ happy ending rather than their better-known magazine party appearance.
24. Poise Magazine Editors Group Costume

Turn the fictional Poise office into a polished group costume. Each person should wear a different early-2000s magazine-editor outfit, including fitted blazers, satin camisoles, pencil skirts, tailored trousers, colorful dresses, and pointed shoes. Jenna can stand out in pink or bright stripes, while Lucy wears black, green, or camel. Style hair with smooth blowouts, sleek updos, decorative clips, or hair sticks. Makeup should include glossy lips, frosted shadow, defined lashes, and rosy blush. Everyone can carry handmade Poise issues, clipboards, press passes, or editorial folders. Add messenger bags and tinted sunglasses for extra Y2K detail. This flexible theme works for groups of any size because every participant can create a complete, distinctive fashion-office look while sharing consistent magazine props.
25. Jenna Rink Slumber Party Costume

Capture the movie’s playful slumber-party atmosphere with a colorful, comfortable Jenna costume. Wear a matching pajama set in pink, blue, or a cheerful print, then layer a fuzzy cardigan or lightweight robe. Add fluffy slippers, bright socks, and a sleep mask worn on your forehead. Style brown hair in loose waves, casual braids, or a slightly messy ponytail. Use fresh makeup with pink blush, mascara, subtle shimmer, and glossy lips. Carry a bowl of colorful candy, fashion magazine, nail polish bottle, or soft pillow as your prop. Avoid making the outfit look like ordinary sleepwear by choosing coordinated colors and recognizable early-2000s accessories. This costume is practical for indoor events and can easily expand into a group look with friends wearing complementary pajamas.
26. Thriller Dance Group Costume

Recreate the memorable party dance with a group wearing colorful early-2000s cocktail outfits rather than frightening costumes. Place Jenna at the center in a rainbow-striped dress, butterfly necklace, pink bag, and metallic heels. Other participants can wear black lace dresses, satin tops, fitted suits, colorful button-down shirts, and polished shoes. Hair should include glossy blowouts, smooth updos, and neat short cuts. Choose party-ready makeup with shimmer, defined lashes, and bright lips, but avoid scary face paint. Everyone can carry a Poise event pass before placing it in a pocket for dancing. Coordinate a simple raised-arm pose for group photos. Bright clothing and recognizable dance positioning make this costume effective without using masks, distressing details, or complicated props.
27. Thirty Flirty And Thriving Costume

Build a birthday-ready costume around Jenna’s famous dream of becoming “30, flirty, and thriving.” Wear a bright pink mini or midi dress with a fitted waist and playful early-2000s shape. Add metallic heels, a butterfly necklace, colorful bracelets, and a sparkly shoulder bag. Style long brown hair in a smooth blowout with two small sections pinned back. Use blue shimmer eyeshadow, mascara, rosy cheeks, and pink gloss. Carry a handmade fashion magazine with the slogan on the cover or wear a simple birthday sash featuring the phrase. A small container of wishing dust makes another useful prop. This complete look is especially suitable for a 30th birthday celebration because it references the movie while still functioning as a festive, flattering party outfit.
28. Poise Magazine Cover Costume

Turn yourself into a walking Poise cover with a glamorous fashion-editor outfit and a lightweight handmade frame. Wear a pink or turquoise cocktail dress with a fitted silhouette, then add matching heels, a bright handbag, and chunky Y2K jewelry. Style brown hair in a voluminous blowout or smooth half-up look. Makeup can include frosted eyeshadow, defined lashes, rosy blush, and glossy lips. Create a large cardboard magazine frame with the Poise title and a few short, fictional cover lines. Hold it around your upper body so the entire outfit remains visible. A press badge can hang from your bag. This costume is easy to understand in photographs and gives Jenna’s magazine career equal attention alongside the movie’s familiar rainbow party dress.
29. Wishing Dust Jenna Costume

A jar of magical wishing dust can become the focal point of a creative young Jenna costume. Wear a pastel floral birthday dress with puffed sleeves, white socks, and simple flats. Style brown hair with curled bangs, fluffy volume, and a pink ribbon or scrunchie. Keep makeup soft and youthful with rosy blush and tinted lip balm. Carry a transparent plastic jar filled with safe, sealed silver paper confetti and label it “wishing dust.” Add a handmade Poise clipping and a friendship bracelet for more story detail. The jar should remain firmly closed throughout the event to prevent spills. This costume is more subtle than the rainbow dress, but the combination of 1980s clothing, birthday styling, and the magical prop creates a clear reference for fans.
30. Razzles Candy Costume

Create a playful candy-inspired costume that still connects clearly to the movie. Wear a bright red or pink T-shirt decorated with a handmade fruit-candy logo, then add a colorful pleated skirt or relaxed jeans. Layer on a cropped blue jacket, striped socks, and clean white sneakers. Style hair in a high ponytail with a multicolored scrunchie. Use pink blush, mascara, and shiny berry lip gloss. Carry an oversized cardboard candy packet or several empty, clean wrappers attached to a small handbag. Keep the graphics homemade rather than relying on a purchased mascot suit. The head-to-toe colors should feel cheerful and early-2000s. This funny costume works alone, but it becomes even more meaningful when paired with young Jenna, Matt, or a group of Poise editors.
31. Jenna Rink Dream House Costume

Reference Matt’s handmade dream house with a romantic Jenna costume. Wear a soft green floral dress with a pink waist ribbon, coordinating cardigan, and comfortable pink or neutral heels. Add a butterfly necklace and small pastel handbag. Style long brown hair in a smooth half-up look with light curls at the ends. Choose rosy makeup, pale shimmer eyeshadow, mascara, and glossy pink lips. Carry a lightweight miniature house made from painted cardboard, complete with bright windows and a small front porch. Keep the model compact enough to hold safely throughout the event. You can also tuck a friendship bracelet around its handle. This thoughtful costume represents Jenna’s emotional connection to her childhood and gives fans a distinctive alternative to her louder fashion-magazine outfits.
32. Y2K Fashion Editor Costume

Capture Jenna’s general Y2K aesthetic with a costume assembled from thrifted fashion pieces. Wear a fitted satin camisole under a cropped blazer, then add bootcut trousers or a colorful knee-length skirt. Choose pointed kitten heels, a small shoulder bag, tinted sunglasses, and a chunky butterfly pendant. Style long brown hair straight with flipped ends or pin back two front sections. Apply frosted blue eyeshadow, thin eyeliner, rosy blush, and high-shine pink lip gloss. Carry a mock magazine, flip phone, and editorial planner. Use pink, turquoise, lime, or purple accents to preserve Jenna’s playful approach to professional clothing. This look does not copy one exact scene, but it remains recognizable as a complete fan-made version of the movie’s colorful magazine-editor wardrobe.
33. 1980s Birthday Party Costume

Create a broader costume inspired by Jenna’s 1987 birthday celebration. Wear a pastel party dress or colorful sweater with a full knee-length skirt, bright tights, and white flats. Add plastic bracelets, clip-on earrings, a friendship pin, and a large scrunchie. Style hair with curled bangs and a high side ponytail or teased half-up shape. Keep makeup light with blue pastel shadow, pink blush, and tinted balm. Carry a decorated birthday invitation, small gift box, or sealed jar of silver paper wishing dust. A handmade magazine page about turning 30 provides the final recognizable detail. This outfit works for guests who want to join a themed group without portraying one exact character and is suitable for school, family, or community events.
34. Jenna Rink Closet Montage Costume

Jenna’s closet excitement can inspire a deliberately colorful costume filled with playful early-2000s details. Wear a bright satin camisole with a patterned mini or midi skirt, then layer a cropped cardigan in a contrasting color. Add a butterfly necklace, stacked bracelets, tinted sunglasses, a sparkly handbag, and metallic heels. Style brown hair straight with small clips or decorative pins. Use pale blue eyeshadow, mascara, strong pink blush, and glossy lips. Carry several lightweight clothes hangers with colorful scarves draped over them, or hold a small garment bag labeled “Poise Party.” Keep the accessories coordinated enough to avoid looking random. The result should suggest someone enthusiastically exploring a glamorous adult closet while styling everything through a cheerful teenage point of view.
35. 13 Going On 30 Family Costume

A family costume can represent several eras and characters from the movie at once. One adult can wear Jenna’s rainbow-striped dress, butterfly necklace, brown half-up hair, and metallic heels. Another can portray Matt in a neutral jacket, button-down shirt, dark trousers, boots, and camera. A teen or child can become young Jenna in a pastel birthday dress, curled bangs, scrunchie, socks, and flats. Another family member can wear young Matt’s striped sweater, jeans, sneakers, and backpack. Add a miniature dream house, Poise magazines, candy packets, and sealed wishing-dust jar as shared props. Keep makeup bright and family-friendly. This coordinated arrangement tells the transformation story clearly and gives every participant a comfortable, recognizable head-to-toe look.
Conclusion:
